A flexible display device is provided, including a flexible display panel which includes a display area, a bending area and a bonding area, wherein the bending area is located between the display area and the bonding area; a first backplate located on a non-display surface of the display area; and a second backplate located on a non-bonding surface of the bonding area; wherein at least one of the first backplate and the second backplate is defined as a backplate structure, the backplate structure comprises a supporting layer and a porous material layer, and the porous material layer is adhered to the flexible display panel at an end of the bending area.

The present invention discloses an assembly of prefabricated wall modular decoration, comprising a conventional decorative material, a plate, a movable laminating layer and a protective layer. The conventional decorative material being mounted on the surface of the plate, a number of movable laminating layers being evenly spaced between the plate and the protective layer making a sound-insulated air gap between them, and the protective layer being mounted on the surface of the wall. The present invention also discloses an installation method for the assembly above. Due to the traditional decorative material, the plate, the active lamination layer, and the protective layer of the present invention are set to be installed on the wall in turn, together with the sound-insulated air gap within the structure, which is not only simple to manufacture and easy to install, but also has better sound absorption performance which could reduce the noise nuisance.

An Methods and apparatuses for reducing the transmission of unwanted sound and vibration energy generated by dynamic and/or impact loads through floors in multi-story buildings. This may be accomplished using an acoustic wave transformation and attenuation sound proofing membrane including an acoustic wave transformation layer, an acoustic absorption layer, and a constrained vibration damping layer. The acoustic wave transformation layer may be capable of transforming acoustic waves in a manner that may easily be attenuated by the acoustic absorption and constrained vibration damping layers. The sound proofing membrane may be used with several different combinations of floor coverings, adhesives, and subfloors. Impact acoustical tests have demonstrated that the sound proofing membrane can achieve higher IIC and MC ratings compared to conventional acoustic underlayments and/or membranes and, thus, prevent unwanted dynamic and/or impact loads from disturbing occupants in rooms beneath the floor assembly.

A display apparatus includes a display panel including a central area and an outer area outside the central area and which is bent. A cover panel includes a cover central area overlapping the central area, a cover outer area overlapping the outer area, a light-blocking layer on the display panel and a groove layer disposed on a first surface of the light-blocking layer opposite to a second surface of the light-blocking layer facing the display panel. A plurality of grooves is defined in the groove layer in the cover central area.

Methods of manufacturing and fixtures for manufacturing containers, particularly for holding cosmetic products, using thin-walled tubes. One end of a container may be formed using an integral process, such as insert molding, while the other end of the container is formed using assembly steps, such as welding, to form a completed cosmetics container from a thin-walled tube.

A method of preparing a green tire innerliner, the method comprising mixing one or more vulcanizable rubbery polymers, less than 0.75 parts by weight zinc oxide, less than 0.75 parts by weight magnesium oxide, and less than 0.75 parts by weight sulfur, per 100 parts by weight rubber, to form a vulcanizable mixture and extruding the mixture to form a green tire innerliner.

A multilayer containment and protection tube for conduits, cables and the like, includes an inner layer made of polymeric material, which is electrically at least antistatic, with a smooth internal surface, which forms a duct for supporting conduits or cables. The tube further includes one or more intermediate layers of electrically at least antistatic reinforcement, an outer layer made of electrically at least antistatic polymeric material, and a covering and finishing layer, which is electrically at least antistatic.

Compositions and methods for preparing at least partially hollow nanoparticles having an outer shell comprising a one or more molecules and/or residues derived from a metal soap, where the nanoparticles each comprise a continuous inner void space that averages at least 10 percent of the volume of each of the nanoparticles. Such at least partially hollow nanoparticles can be employed in a variety of applications including, but not limited to, tire manufacturing.
